Certain of the functions andsteps provided in the Figures may be implemented in hardware, softwareor a combination of both and may be performed in whole or in part withinthe programmed instructions of a computer. No claim element herein is tobe construed under the provisions of 35 U.S.C. 112(f), unless theelement is expressly recited using the phrase “means for.” In addition,an artisan understands and appreciates that a “processor” or“microprocessor” may be hardware in the claimed disclosure. Under thebroadest reasonable interpretation, the appended claims are statutorysubject matter in compliance with 35 U.S.C. § 101.

According to an embodiment, the electronic device 100 may be referred toas a smart phone, a table personal computer (PC), a PC computer, or thelike. Referring to FIG. 1, although the electronic device 100 isexemplified as a smartphone herein, the present disclosure is notlimited thereto. For example, in another embodiment, the electronicdevice 100 may be a wearable device. The at least one processor 110 mayinclude an application processor (AP), a central processing unit (CPU),a communication processor (CP), or the like.

According to an embodiment, the electronic device 100 may be coupled toa wearable device 200, thereby directly controlling the wearable device200.

According to an embodiment, the communication circuit 120 may beconfigured to communicate with at least one wearable device 200. Theelectronic device 100 may form a communication channel with the wearabledevice 200 through the communication circuit 120 to be connected withthe wearable device 200 either via a wire or wirelessly. The electronicdevice 100 may transmit control signals, data, or the like to thewearable device 200 through the communication circuit 120.

According to an embodiment, the wearable device 200 may include aprocessor 210, a communication circuit 220, and an actuator 240.Additionally or alternatively, the wearable device 200 may furtherinclude a display 230 to provide, for example, visual user interfacesrelated to haptic feedback. The processor 210 of the wearable device 200may communicate with the electronic device 100 through the communicationcircuit 220. The processor 210 may also drive the actuator 240, therebyoutputting haptic feedback having a specific pattern.

According to an embodiment, the electronic device 100 may generate acontrol signal for controlling the wearable device 200 based on theposition where the wearable device 200 is placed, and/or informationregarding the actuator 240, such as vibration characteristic of theactuator 240, whether the actuator 240 is a linear resonance actuator(LRA), an eccentric rotating mass (ERM) vibration motor, a DC motor,etc. The control signal may then be transmitted to the wearable device200 so that the wearable device 200 outputs haptic feedback having aspecific haptic pattern. The wearable device 200 may then output thehaptic feedback having the specific haptic pattern in response toreceiving the control signal.

In another example, the electronic device 100 may determine a hapticpattern corresponding to content reproduced or executed and may changethe determined haptic pattern into the form (e.g., by changing at leastone of amplitude and frequency of the haptic pattern) corresponding toat least one of the position of the wearable device 200 on the user'sbody and the vibration characteristic of the wearable device 200, suchas the type and size of the actuator 240. The electronic device 100 maytransmit a control signal corresponding to the changed haptic pattern tothe wearable device 200 and the wearable device 200 may output hapticfeedback in response to the control signal.

According to an embodiment, the wearable device 200 may operate as ahaptic feedback device for the electronic device 100. In this case, thewearable device 200 may disable other operations or functions, forexample phone call function, alarm function, biometric sensor signalcollecting function, or the like.

According to an embodiment, the electronic device 100 may furtherinclude a display 130 and a memory 140. For example, the electronicdevice 100 may provide several interfaces, which are to be describedwith reference to FIGS. 5 to 7, through the display 130. The electronicdevice 100 may store, in the memory 140, data required to generate thecontrol signal to be transmitted to the wearable device 200.

FIGS. 2A and 2B illustrate an operating environment of the electronicdevice, according to an embodiment.

According to an embodiment, at least one processor 110 may identify atleast one wearable device 200 connected with the electronic device 100.The electronic device 100 may obtain information on the position on theuser's body where the at least one wearable device 200 is placed(wearing position).

For example, the information on the position where the wearable device200 is placed may be referred to as information of a body part of theuser where the wearable device 200 is positioned. Referring to FIG. 2B,the wearable device 200 may be put on the head, the neck, the wrist, thechest, the waist, the arm, the hand, the leg, the foot, etc., of theuser.

According to an embodiment, an output for a specified haptic pattern maybe requested for a particular various function that is executed by theelectronic device 100. For example, the specified haptic pattern maycorrespond to specific content (e.g., images, games, VR content, or thelike) reproduced or executed by the electronic device 100. The specifiedhaptic pattern may include information on a part of the body that willreceive the haptic pattern, intensity of the vibration, period of thevibration, duration of the vibration etc. The haptic pattern may bepreviously associated with the content so as to enrich user experience.

According to an embodiment, if the output of the specified hapticpattern is requested as at least one function is executed, theelectronic device 100 may control the wearable device 200 such that thewearable device 200 outputs haptic feedback corresponding to thespecified haptic pattern. For example, the electronic device 100 maygenerate a control signal corresponding to the specified haptic patternand the position where the wearable device is placed and may transmitthe control signal to the wearable device 200. The wearable device 200may output the haptic feedback corresponding to the control signal.

According to an embodiment, the specified haptic pattern may include aposition list of the positions where the haptic feedback occurs. Forexample, the position list may include a plurality of target positionsfor producing a haptic effect. The electronic device 100 may select thewearable device 200 among various wearable devices based on a particulartarget position in the position list.

According to an embodiment, even if the same haptic pattern isspecified, different haptic feedback may be output depending on wherethe wearable device 200 is located. That is, the specified hapticpattern may be altered depending on the position on which the wearabledevice 200 is placed. For example, the electronic device 100 may obtaina setting value for altering the specified haptic pattern based on thewearing position of the wearable device. Then, the electronic device 100may generate the control signal based on the obtained setting value. Thesetting value may, for example, be previously stored in the electronicdevice 100 or received from an external device (e.g. a server).

Referring to FIG. 2A, by way of example, the electronic device 100 isconnected with a first device 201 placed on a left arm, a second device203 placed on the head, and a third device 205 placed on a right hand.The electronic device 100 may identify the first to third devices 201 to205 when they are connected with the electronic device 100. Theelectronic device 100 may obtain “the left arm” as position informationof the first device 201, “the head” as position information of thesecond device 203, and “the right hand” as position information of thethird device 205.

In one example, as a function (e.g. VR function) of the electronicdevice 100 is executed, output of a haptic pattern having the samevibration intensity may be requested with respect to the first device201 to the third device 205. But the electronic device 100 may controlthe first device 201 to the third device 205 to output different hapticfeedback based on the positions of the wearable devices. For example,the electronic device 100 may cause the second device 203 to outputvibration having the weakest intensity, because it is placed on the headof the user. That is, due to sensitivities in the head region of theuser, to provide tactile sensation of the same intensity as feedback toanother part of the body, haptic feedback provided to the head of theuser may have to be weaker.

If output of the haptic pattern is requested only with respect to thehand and the arm, on the other hand, the electronic device 100 maytransmit control signals only to the first device 201 and the thirddevice 205. Accordingly, a particular tactile effect may be transmittedto only some body parts by the electronic device 100.

FIG. 3A is a flowchart illustrating a haptic operating method for theelectronic device depending on positions of the wearable devices,according to an embodiment. FIG. 3B is a flowchart illustrating a hapticoperating method for the electronic device depending on vibrationcharacteristics of the wearable devices, according to an embodiment.

Referring to FIGS. 3A and 3B, according to an embodiment, the method forcontrolling the wearable device 200 may include operation 310 tooperation 350. Operation 310 to operation 350 may be performed by theelectronic device 100 illustrated in FIG. 1. Each of the operations 310to 350 may be implemented with instructions being able to be performed(or executed) by the processor 110 of the electronic device 100. Theinstructions may be stored, for example, in a computer-recording mediumor the memory 140 of the electronic device 100 illustrated in FIG. 1. Inthe following description of operations 310 to 350, reference numeralsof FIG. 1 are used and descriptions duplicative of those of FIG. 1 willbe omitted in order to avoid redundancy.

In operation 310, the electronic device 100 may identify at least onewearable device 200 connected with the electronic device 100. Forexample, the electronic device 100 may search for and identify thewearable device 200 so that the wearable device 200 is connected withthe electronic device 100 for providing haptic output.

In operation 320, the electronic device 100 may obtain information onthe position on which the wearable device 200 is placed. If output for aspecified haptic pattern is requested as a particular function isexecuted in the electronic device 100, in operation 340, the electronicdevice 100 may transmit a control signal to the wearable device 200 suchthat the wearable device 200 outputs haptic feedback corresponding tothe position information and the specified haptic pattern. Thedescriptions of operation 320 and 340 have been described with referenceto FIGS. 2A and 2B.

In operation 330, the electronic device 100 may obtain vibrationcharacteristic information output by the actuator 240 included in thewearable device 200, which is connected with the electronic device 100.In operation 350, the electronic device 100 may transmit a controlsignal to the wearable device 200 such that the wearable device 200outputs haptic feedback corresponding to the vibration characteristicinformation and the specified haptic pattern. For example, the vibrationcharacteristic information may include information on the types ofhaptic pattern that may be outputted by the actuator 240 based onhardware characteristics of the actuator 240.

According to an embodiment, even if the same haptic pattern isspecified, different haptic feedback may be outputted depending on thecharacteristics of the actuator 240. The frequency band or the reactivespeed of the haptic feedback may be different depending on the types ofactuators 240. For example, a linear resonant actuator (LRA) may outputhaptic feedback with shorter periods as compared to a direct current(DC) actuator.

The electronic device 100 may change the specified haptic pattern to ahaptic pattern which is able to be outputted by the actuator 240. Theelectronic device 100 may generate a control signal corresponding to thechanged haptic pattern and may transmit the control signal to thewearable device 200.

For example, the electronic device 100 may generate a control signal byusing change information for changing the specified haptic pattern suchthat the specified haptic pattern is differently output depending on thevibration characteristic of the actuator 240. For example, the changeinformation may be stored in the memory 140 of the electronic device100. In addition, the change information may be received from anexternal device (e.g., a server).

According to an embodiment, operation 320 and operation 330 may besimultaneously performed. That is, the electronic device 100 maysimultaneously process the specified haptic pattern, the position of thewearable device 200, and the vibration characteristic of the wearabledevice 200. The position information and the vibration characteristicinformation of the wearable device 200 may be obtained from the wearabledevice 200. Using the position information and the vibrationcharacteristic information, the electronic device 100 may generatehaptic feedback suitable for the position of the wearable device 200 andsuitable for the actuator 240. The electronic device 100 may transmitthe control signal to the wearable device 200 such that the wearabledevice 200 outputs the haptic feedback corresponding to the positioninformation, the specified haptic pattern, and the vibrationcharacteristic information.

For example, the electronic device 100 may change the specified hapticpattern, based on the position of the wearable device 200 and/or thecharacteristic of the actuator 240. Thus, the electronic device 100 candynamically alter the specified haptic pattern so that proper hapticfeedback can be outputted by the wearable device 200 even if differentdevices with different vibration characteristic are used as the wearabledevice 200.

FIG. 4 is a flowchart illustrating a method for obtaining positioninformation of a wearable device, according to an embodiment.

Referring to FIG. 4, according to an embodiment, the method forobtaining the position information of a wearable device may includeoperation 410 through operation 420. Operation 410 through operation 420may be performed by the electronic device 100 illustrated in FIG. 1.Each of operation 410 and operation 420 may be implemented withinstructions being able to be performed (or executed) by the processor110 of the electronic device 100. Hereinafter, reference numerals ofFIG. 1 may be employed in the description made with reference of FIG. 4.

Operation 410 may correspond to operation 310 of FIG. 3A and FIG. 3B.The duplicative description thereof will be omitted.

In operation 415, the electronic device 100 may obtain informationassociated with the position on the user's body where the wearabledevice 200 is placed. In operation 420, the electronic device 100 maydetermine the position of the wearable device 200 based on the obtainedassociated information, thereby obtaining the position information.

According to an embodiment, the associated information of operation 415may be motion information of the wearable device 200. The electronicdevice 100 may obtain position information based on the motioninformation.

In another example, the electronic device 100 may determine the positionof the wearable device 200 based on data obtained through a sensor(e.g., a gyro sensor) of the wearable device 200. The data may include adirection in which the wearable device 200 moves, or the like.

For example, the movement data corresponding to a body part wearing thewearable device and a wearing direction (leftward or rightward) may bepreviously computed. The electronic device 100 may store the previouslycomputed movement data in the memory 140 or may receive the previouslycomputed movement data from an external device (e.g. a server). Theelectronic device 100 may compare the previously computed movement datawith movement information obtained from the wearable device 200, therebydetermining the position of the wearable device 200.

According to an embodiment, the associated information of operation 415may be user input. The electronic device 100 may obtain the positioninformation based on the input. For example, the electronic device 100may directly receive an input stating that, for example, the wearabledevice 200 is placed on the left arm of the user.

According to an embodiment, the associated information of operation 415may include information on the type of the wearable device 200. Forexample, the information on the type of the wearable device 200 may bereceived from the wearable device 200 and may be stored in the memory140 of the electronic device 100. The electronic device 100 may obtainthe position information based on the type of the wearable device 200.For example, when the wearable device 200 is a head-mount device, theelectronic device 100 may determine that the wearable device 200 ispositioned on the head of the user 50.

According to an embodiment, the electronic device 100 may obtain theposition information by using a biometric sensor mounted in the wearabledevice 200 and bio information obtained from the biometric sensor.

For example, the electronic device 100 may determine the wearingposition based on the type of sensor mounted in the wearable device 200.The wearable device 200 including a fingerprint sensor may be determinedas being placed on a finger of the user. The wearable device 200including an iris sensor may be determined as being placed on the faceof the user. The wearable device 200 including a heart rate sensor maybe determined as being put on a wrist of the user.

For example, the electronic device 100 may obtain position informationby using bio information obtained from the mounted sensor. When thefingerprint information is obtained, the wearable device 200 may bedetermined as being put on the finger. When the heart rate informationis obtained, the wearable device 200 may be determined as being put onthe wrist.

According to an embodiment, the electronic device 100 may obtain theposition information based on the combination of information related tothe biometric sensor and the movement information.

For example, when the electronic device 100 obtains information on theheart rate of the user, the electronic device 100 may determine thewearable device 200 as being placed on the wrist of the user. Based onmovement data, the electronic device 100 may determine whether thewearable device 200 is placed on the right wrist or the left wrist.Thus, the electronic device 100 may determine the position on which thewearable device 200 is placed by using a combination of biometricinformation and the movement information.

FIG. 5 is a view illustrating an interface to obtain motion informationof the wearable device, according to an embodiment.

According to an embodiment, the electronic device 100 may output ascreen for inducing movement of the wearable device 200 through thedisplay 130 of the electronic device 100 or the display 230 of thewearable device 200. The electronic device 100 may determine theposition of the wearable device 200 by using movement informationobtained.

Referring to FIG. 5, the electronic device 100 may display the list ofwearable devices 200 connected with the electronic device 100 asillustrated through screen 510.
